I mean, there is very short launch window, during which station’s flight path is directly over the launch pad. Within few degrees, I guess. Once cleared the tower, shuttle performs a roll maneuver. At that point, just about 20 seconds after launch, shuttle is already in the plane of orbit and it can’t be changed much. The only thing done from here is acceleration, so perigee of that particular orbit move out of center of Earth. In that very nice picture I see, that trajectory of Atlantis is not directly towards station. Why so?
